CO2 Liquefaction / CO2 Recovery
In addition to the production of biomethane the Bright Renewables systems may be used to recover and liquefy CO2 to create an extra source of revenue for the owner of the biogas plant with biogas upgrading system. Zero methane slip is achieved since the small amount of methane still present in the CO2 is recovered during the liquefaction process. When no liquid CO2 production is required, the recovery system can be put in a stand-by mode that requires no additional energy.
Extra source of revenue!
By extending the Bright Renewables system with a CO2 recovery module the gaseous CO2 that is produced during the upgrading can be liquefied. This liquid CO2 has food grade quality and can be used in:
